Every week, Food52's Executive Editor Kristen Miglore is unearthing recipes that are nothing short of genius. Today: The most foolproof way to cook any fish—and a petition for a new cooking term.
The most unfair implication of slow-roasting is the slowness part. Sure, there are plenty of benefits—gentler cooking, a cooler kitchen, a both technique- and zen-driven lifestyle—but speed (and, by association, weeknight-friendliness) isn't one of them. Or is it?

Unlike slow-roasted pork or chicken or even tomatoes, the perks that come along with turning down the oven happen to come much faster with fish, as most things do. Fish needs a new marketing campaign: Fish is always fast. Its connective tissue and protein structure are more delicate than those of other meats, says Harold McGee, and should generally be cooked as little as possible.
And so, fish is the only case where slow-roasting can take as little as 15 minutes. Low-roasting would be more accurate than slow-roasting—we should start seeding a change in terminology, and tell Google about it.
But perhaps the simplest, fastest, and most versatile slow-roasting technique comes from Sally Schneider in A New Way to Cook. All you need: a thin coat of olive oil, salt, and a 275° F oven.
Schneider learned about the technique for salmon close to 20 years ago, she wrote to me, "So I asked, 'What if I applied it to other fish?' and tested them out to discover that the dead-simple technique works great for all sorts of fish and shellfish"—from striped bass and cod to sea scallops to steakier fish like tuna and swordfish.
Slow-roasting makes a beautifully tender, evenly cooked, not-one-bit-dry piece of fish. If you miss the 120° F, just-starting-to-flake mark, it will still be good—even carryover cooking after taking it out of the oven won't outrun you, because there isn't much velocity behind it. This makes the technique perfect for dinner parties and newer fish cooks, whom the "Fish is always fast" marketing will hopefully reach soon.
"Over the years, it’s proven to be an essential technique I’ve riffed on endlessly," Schneider told me. "You slow-roast the fish, then embellish it any way you want or with whatever is on hand; therein lies the opportunity to improvise." In her later version in The Improvisational Cook, she suggests all kinds of sauces, from fennel oil to brown butter and vinegar. I topped mine with Greek yogurt speckled with chives.
Years ago, I learned a memorable analogy about speed and cooking from my friend Anita Shepherd, after I burned a pan of bacon and had to ride my bike around Little Italy looking for another package late at night—this was before she became a vegan chef and coconut milk yogurt developer (and before I cooked bacon for dinner more often than I should).
She told me cooking is like coming up to a stop light. If you're going slowly, it's easy to hit your mark. If you're going fast, you'd better hope that you have very good aim (and strong brakes). Low (née slow) roasting is fish's built-in brake.
1 teaspoon extra-virgin olive oil 1 1/2 pounds thick salmon fillet, or other fish like striped bass or cod (1 large fillet or four 6-ounce fillets) Kosher salt A small bunch of fresh thyme sprigs (optional) Chopped fresh herbs like chives, and Greek yogurt to finish (optional)

I'm an ex-economist, ex-Californian who moved to New York to work in food media in 2007. Dodgy career choices aside, I can't help but apply the rational tendencies of my former life to things like: recipe tweaking, digging up obscure facts about pizza, and deciding how many pastries to put in my purse for "later."
